Full textAbstract:
This research study is more of an initiative towards Social Impact Assessment of copper-nickel mining in Botswana. The specific objectives of the study were centred on the assessment of the social impacts of copper-nickel mining in Botswana from the initial mining stage of exploration, surveying and mine site development to mine closure. The study was carried out under the broad hypotheses that mining influences population movement that impact on areas of mining; mining activities have both economic benefits and deleterious social impacts on the local communities found in the areas where mining is taking place; and mine closure has far reaching socio-economic, investment and developmental implications over and above the obvious interests of project owners. To achieve the broad aim as summarised above, the research study used a multi-disciplinary methodology and approach that required several kinds of expertise and sources of information. Hence it used both primary and secondary sources centred on interactive informative interviews, site visits and observations, questionnaires, census data records, mining companies’ publications, published textbooks and journal articles. The research study comprised of three different mines operated by three different mining companies in three varied socio-cultural and ethnic regions of Botswana. First was a detailed Social Impact Assessment of the initial phase of exploration, surveying and mine site development represented by Mowana mine project operated by African Copper in the rural areas of Dugwi and Mosetse. This case study yielded results showing that the social impacts of mining in the area are diverse and extensive. The findings suggest that the impacts relate not only to the possible economic benefits of foreign exchange, employment, the optimal use of available mineral resources and the possible development of Dugwi and Mosetse villages, but extends to the deleterious social impacts. The results also indicated that the social impacts have just begun in the two communities. Hence they point towards a possible disruption within the socio-cultural system of the local people if serious mitigation measures are not put in place; thus suggesting that the early stages of exploration and mine site development results in the most conflict between the mine and the local people. Second was a comprehensive Social Impact Assessment of Tati-Nickel Phoenix mining project in the peri-urban areas of Matshelagabedi and Matsiloje areas representing the mining stage of mine production and expansion. The results from this case study suggest that during vi mine production and expansion, many people were relocated. However, the overriding impression gained from the case study was Tati-Nickel Mining Company’s elaborate corporate policies that suggested good corporate governance and best practices that promote sustainable development. A notable milestone on good corporate governance and best practice that the other two case studies (mining company) could benchmark on is Tati-Nickel’s corporate social responsibility programme that has been designed to ensure that the communities within a fifty kilometre mine radius benefit from the mine. The results from the case study also distinguished the mining stage of production and expansion from the other two because it is associated with the deep entrenchment of the social impacts into the communities near to mining areas. Third was a detailed Social Impact Assessment on Bamangwato Concession Limited mine in the industrial town of Selebi-Phikwe. The case study represented the stage of mine closure. Through the findings of this case study, it became apparent that the economic dependence of Selebi-Phikwe on mining has seen the town developing into a mining town, increasing its vulnerability at mine closure. The results from the case study further suggest that mine closure will degrade the socio-economic sector of the town with ever far reaching socio-economic implications as many people lose their gainful employment, hence suggesting that a possible complete mine closure will be the most traumatic phase leading to major social conflict within the area. Thus the results suggest that at mine closure, the deleterious social impacts will overspill to other areas in Botswana with disastrous effects for the economy of the country. The results yielded through this study established in clear and passionate language that copper-nickel mining in Botswana influences population movements that lead to positive and negative impacts on the communities found in mining areas. Another major finding of the study is that copper-nickel mining activities have both economic benefits and deleterious social impacts on the local communities, hence the recommendation that the copper-nickel mining companies should embrace the concept of sustainable mining for sustainable development to avoid most of the negative impacts of their operations on the local communities.

Employees are known to develop and use key process improvements. In this thesis, I explore innovation by mining employees working in Codelco, a Chilean mining company. The data on these innovations come from a contest sponsored by mine management at the Andina division of Codelco. This contest encourages workers to come forward and reveal the improvements they have made. The research method used for this case study is based on data and information collected from interviews with managers, workers and members of the contest organizing committee. In addition, a survey was given to more than 50 workers involved in the current version of the contest, to evaluate and analyze their interests and motivation drivers to participate in the contest. One of the main findings is that more than 85% of total workers do behave as user innovators, and 85% of the survey's participants have created at least two innovations at Andina. For the workers, the main reasons to participate in the contest are making a contribution to the company, to develop a deeper knowledge in a specific topic, and also to be recognized by family, colleagues and managers. The key lessons of this case study are that user innovations in the copper mining industry do happen, and creating the right incentives for workers to innovate and share their innovations, can increase their motivation, performance evaluation and add value to their company and the industry.

Full textAbstract:
The mining industry in Arizona first gained prominence with the growth of the Morenci-Clifton district in the 1870s. A "Mexican camp" from its inception, the town differed racially from the other mining centers across the State, most notably that of Bisbee to the south. As the industry expanded and with the coming of the 20th century, each town established its reputation as an ethnic center for Mexicans and Anglos. Competition for jobs and debates over the rights of workers both contained an underlying issue of race. Questions about who held rights to which jobs isolated Morenci-Clifton as a cultural outlier, and the union push to regulate the industry left the region in a precarious situation. A 1903 state law shortening the work day to eight hours prompted the first major strike in the history of the district, and the motivations behind the law's passage had connotations beyond the protection of workers, extending into the realm of racial exclusion.

Full textAbstract:
The rise of market globalization creates challenges for business executives seeking to pursue foreign direct investment (FDI) in least developed countries (LDC), such as Afghanistan. Multinational corporate (MNC) executives need strategies that will improve the timely delivery of minerals for mining projects in LDCs. Guided by the force field analysis theory, the purpose of this holistic, single-case study was to explore the strategies that 5 MNC executives in Beijing, China, used to improve the timely delivery of minerals associated with the Aynak copper mine project in Afghanistan. Semistructured interviews were used to elicit detailed narratives from MNC executives about their experiences to develop strategies for mining projects in LDCs. A review of company documents, as well as member-checking of initial interview transcripts, helped to bolster the trustworthiness of final interpretations. Study results included 2 themes. Theme 1 was determinants of mine investment strategies in LDCs that included an exploration of driving forces, restraining forces, neutral forces, and the effect of those forces. Theme 2 was FDI strategies for copper mine projects in LDCs that included the comparison of cost leadership strategy, differentiation strategy, and combination of cost leadership and differentiation strategies. By implementing a cost leadership strategy and best practices, MNC executives were able to achieve greater success to improve timely delivery of minerals associated with FDI copper mine projects in LDCs. Social implications include ongoing efforts of Afghan government leaders to implement effective economic policies that decrease unemployment while reducing poverty.

Full textAbstract:
Background:
Over the last three years uranium prices have soard from US $14 per pound (lb) to the current price of US $120/lb and this rapid incline of the commodity have created a boom within the uranium prospecting and min-ing industry. There are currently 435 nuclear reactors all over the world and these reactors demand 180 millions of pounds of uranium each year to run at full production. Currently the uranium mining industry only sup-plies 110 million pounds of the demanded quantity. The remaining 70 mil-lion pounds are coming from secondary sources such as decommissioned nuclear warheads and other sources. Market estimations say that the sec-ondary sources will only cover the shortage up until around 2012 then primary sources have to supply almost the whole quantity demanded. These factors imply that some sort of analysis model for uranium mining companies would be needed.
Purpose:
The purpose of this report is to valuate three companies within the ura-nium industry and to establish if the current market value is coherent with the fundamental value of these companies. The authors will propose a valuation model that could be used when valuating companies within the uranium industry.
Method:
A qualitative method has been used in order to value three companies within the uranium mining business that are fairly large players on the market. The valuation of these companies is based upon a discounted cash flow analysis, a relative PV valuation and relative valuation. The compa-nies included in the report are corporations that are quoted at Toronto Stock Exchange and they have started mining uranium. Data have been collected through annual reports and the companies Internet pages. Other secondary information such as valuation theories has been collected from academic search engines and books on the subjects.
Conclusions:
The current market values of uranium mining companies are not coherent with the actual fundamental values according to the authors. Both funda-mental and a comparative approach could be used when valuing these companies and the most important part in the valuation is to try and fore-cast the commodity price and then to estimate the companies possible mining reserve/extractable resources.

Full textAbstract:
Geopolymerization is a chemical reaction process, reacting SiO₂ and Al₂O₃ with alkaline solutions, which can transform aluminosilicate solids or particles to polymer materials. Geopolymers have many engineering applications such as cementation binders for construction and solidification or encapsulation of hazardous heavy metals. Mine tailings mainly consist of SiO₂ and Al₂O₃. Theoretically, mine tailings can be used as source materials for geopolymerization. However, for most researchers, they use fly ash, metakaolin or furnace slag as source minerals, because these minerals are much more reactive with alkaline solutions. Mine tailings are naturally-forming minerals and are considered to be inert in geopolymerization. How are mine tailings to be activated through different reaction conditions? We conducted several tentative or preliminary experiments to study the geopolymerization process step by step. We tried different methods to react mine tailings with alkaline solutions. Mine tailings were submerged into alkaline solutions in a plastic bucket for 6 days in room temperature (20-25 °C). We wanted mine tailings to be activated by soaking. The results were not satisfying. Then we tried to react mine tailings with alkaline solutions at 60 °C and 90 °C. After analyzing, we found that the results were not satisfying either. So, we conducted simplified geopolymerization experiments in order to better understand the chemical reaction mechanism. Pure SiO2 and Al2O3, which were two major reactants, were employed to simplify and simulate the geopolymerization process. We drew some useful conclusions such as that geopolymerization took place at elevated temperatures; Al₂O₃ almost did not react with alkaline solutions at low temperatures, etc. We conducted experiments at elevated temperatures (150 °C, 180 °C, 210 °C). Different levels of pressure (5 MPa, 10 MPa, 20 MPa) were applied to make compact specimens. After many attempts, the results were successful. The highest mechanical strength was about 20 MPa. Most importantly, we obtained polymers produced from geopolymerzation, which could be seen by naked eyes. The experiment techniques such as scanning electron microstructure (SEM) imaging and X-ray diffraction (XRD), inductively-coupled plasma mass spectrometry (ICP-MS), and unconfined compression tests (UCS) were applied to study the geopolymerization reaction mechanism and the feasibility of using mine tailing-based geopolymers as construction materials.

Full textAbstract:
The objective of this investigation was to experimentally determine the variation in the flow characteristics of tactite copper ores during the leaching process. The laboratory work involved estimation of porosity and permeability of cores before leaching, and after various intervals of leaching. The tests were carried out using specimens of diameter 1.5 and 4.0 inches, prepared from boulders obtained from the Cyprus Casa Grande mine. A solution containing about 25 grams of sulfuric acid per liter was used as the lixiviant. Porosity was determined using the water saturation method. The permeability was estimated using either helium or water with the specimens stressed triaxially to simulate in situ conditions. The rate of copper recovery from the specimen during the leaching process was also determined by estimating the copper content in the solution used for leaching. The results indicate that the permeability and porosity of the specimens increased with leaching, but both tend to remain constant after most of the soluble material in the core was dissolved. The rate of copper recovery was high initially but dropped as leaching progressed and the copper in the specimen was depleted.

Full textAbstract:
The objective of this research is to describe the nature of an outsourcing in mining industry and the main focus of outsourcing will be in the characteristics of outsourcing decision-making and its implications on outsourcing decision-making process. Mining industry sector is offering interesting facets for outsourcing as a practice due to the remote locations, mine lifecycle, limited and specified supply market and challenging production.
The theoretical contribution of this research creates knowledge from the typical elements of the outsourcing decision in mining industry and shows where the motivators and factors are typically encountered in such decisions, and how they affect to the outsourcing process.
In this research qualitative research methods are used. The theoretical framework is created by combining pre-existing outsourcing literature of outsourcing process and outsourcing decision-making. The theoretical framework is used to support the empirical data collection, analysis and formation of the theoretical conclusions. The empirical part consist a multiple case-study with two research cases from a mining industry. Interviews were the main empirical data used.
As a result of this study, outsourcing in mining industry is guided by two contextual factors: the production factors and the capacity-based factors. Production related decisions occur more often in the strategic level of outsourcing decision and capacity-based outsourcing decisions in the tactical level. Therefore the outsourcing decision is the groundwork of firm’s capability base and a risk perspective. The strategic risk assessment is to identify how critical outsourced processes are to the organization. For the capability evaluation, several actors have been recognized to have an impact on outsourcing decision. This research also reveals that in some situations, for example in limited market with high uncertainty, the supplier capability can have an overall impact on outsourcing decision of the company.
This research provides useful insights for outsourcing managers to evaluate their outsourcing decisions. The study reveals that it is important to understand both internal and external environment of the outsourcing decision and the strategic and structural aspects associated with an organization’s decision to reconfigure.

Full textAbstract:
Accurate ore estimation processes are of crucial importance in the mining scenario. Over the last 20 years, one practical approach to improve ore grade estimation has encouraged the need to incorporate the geology of the ore deposit being estimated in the estimation process. The objective of this study is to investigate the impact of the geology on the kriging estimation of the ore grade of a portion of a porphyry copper deposit. Preliminary data analysis demonstrates the need to perform a subsequent variogram modeling and kriging estimation of the ore grade by rock type separation. Global and local estimations were done to assess the influence of the geology on the ore grade estimation at a global and local scales. The results obtained in this study demonstrated that for the portion of the deposit studied the incorporation of the geology does not produce substantial improvement on the ore grade estimation.

Full textAbstract:
In the current study, copper nanowires are fabricated by filling the nanochannels of anodic aluminium oxide (AAO) templates using electrodeposition. The nanowires with different growth orientations as well as twin boundaries in some cases are obtained. Cu micropillars are machined from bulk materials using focused ion beam (FIB) milling. The micropillars oriented in the [235] and [156] directions, with and without a twin boundary, with a cylindrical or square shape and with different sizes are prepared. These pillars are then compressed by a nanoindenter equipped with a flat tip, and the stress-strain curves are obtained. The morphologies of the pillars are observed using scanning electron microscopy (SEM). Thin foils of the pillars are prepared by FIB and examined using transmission electron microscopy (TEM) and scanning TEM (STEM). Finally, the dislocation structures are analysed to shed light on the investigation of the deformation mechanisms.

Full textAbstract:
This research is a Master’s thesis that has made for Parker Hannifin Oy in the University of Oulu in Department of Process and Environmental engineering. Parker Hannifin Oy ordered a market research of the Finnish mining market. A subject was a limited research to the northern Fennoscandian and Greenland mining market but the main focus is in Finnish mining industry and technology market. The research produced new information about the mining market for the decision makers of Parker Hannifin Oy. The research problem was to clarify which delivery models would work with mining industry, what is the commercial potential with mining industry and which are the technology areas where the supply of Parker Hannifin Oy and the demand of the mining industry would meet.
Qualitative and quantitative methods were used in the market research. A sample for market research was collected from public sources and with interviews and questionnaires. The market research begun with desk research in which the researcher investigated the mining market by public information. After this there were a qualitative interviews and questionnaires for the mining industry and for the company which ordered of research. The data sample was treated with qualitative research methods.
The commercial potential for Parker Hannifin Oy is huge in Finnish and Swedish mining market. The mining is developing and growing very fast in both countries. It was estimated that Parker Hannifin Oy could be increased their revenue 10 % by sales to Finnish mining industry in 2012. It has been estimated that the production of Finnish mining industry will triple by the year 2022. Also, the Swedish mining industry will need 10 000–15 000 new employees by year 2025 which two or three times more than Finnish mining industry. The potential mining industry customers considered that site container and a spare part store of mining company are efficient and effective delivery models. One result of the questionnaire was that most of the Finnish mining companies have a store of critical spare parts of mining machines. Products of Parker Hannifin Oy are mostly used in underground mining machines in Finland. In the research came out that the easiest way for Parker Hannifin Oy to increase its sales could be by finding cooperation partners from those local stores and contactors which already do business with local mining companies.

Full textAbstract:
The adoption of lithium-ion and/or super-capacitor battery technologies is a current hot topic in the automotive industry. For both battery types, the terminals and busbars are manufactured from copper (Cu) and/or aluminium-based (Al-based) alloys, as a result of their high electrical and thermal conductivities. Laser welding is considered an attractive process to industry due to its easy auto-motability, high processing speed and highly repeatable cost-effective processing. However, laser welding of monometallic and dissimilar Cu and A1 presents several difficulties due to the high surface reflectivity at infrared (IR.) wavelengths. Three main areas were investigated in this research work: • Laser beam lap-welding of monometallic Cu sheets, with the aim of validating the developed welding procedures against target specifications addressed by the automotive industry, in line with production environment setups. • The suitability of using tailored energy distributions, produced using a 1070nm laser source delivered through a laser beam scanner, for welding multiple overlapping Al or Cu foils. • The effects of different laser processing parameters on the formation of deleterious brittle intermetallic phases when welding Alto Cu with a continuous-wave Yb-fibre laser.

Full textAbstract:
Most recent studies of the relationship between technological change and mining labour in the western metal-mining regions of North America have concentrated on the impact of the mechanization of the industry that took place during the second half of the nineteenth century. The distinct impression is left that the increased use of machinery — especially the machine drill — was the chief factor in reducing the skill levels associated with mining as a craft tradition. Preoccupation with machinery has led to the assumption that by the beginning of the twentieth century the transformation to modern forms of mining was essentially complete and the traditional miner an anachronism.
Mining as practiced prior to 1900 differed qualitatively and quantitatively from the subsequent period of "modern mining;" but the introduction of machinery per se was less important to the reorganization of the patterns of work in the mines than the redesigning of the engineering systems in which workers and machines were employed — a process which gained its full momentum in the decades after 1900. This transformation involved the gradual abandonment of low-volume, high-value, selective mining methods in favour of higher volume, non-selective methods which emphasised the quantity rather than the quality of the ore mined. The change redefined the nature of work in and around the mines, putting an end to a tradition of mining practice that was at least as old as the methods described in Agricola's De Re Metalica, something the initial mechanization of mining had never been intended to accomplish.
Under selective mining practices, machinery was used to assist the skilled miner in his traditional task. Under non-selective or mass mining techniques, a new generation of engineers trained in the applied sciences redefined the miner's work as solutions were sought to the problems of an increasingly complex geology in a climate of rapid economic expansion, chronic over-production, generally declining metal prices, and ever increasing production costs. The efforts and successes of these engineers were amply demonstrated in the fields of mining, metallurgical, and human engineering. The impact of the change is evident in varying degrees throughout the metal-mining community; but by focusing on copper mining — the technological leader from 1900 to 1930 — the full impact of the industrial sciences on mine labour is evident.Arts, Faculty of

Full textAbstract:
Mining is a significant economic driver in British Columbia (BC). There has been a long history of copper mining in BC and with a strong forecasted global demand for copper it remains an important socio-economic opportunity. In the last 15 years, only one copper project has progressed beyond the federal-provincial review system to proceed into production. Why has it been so difficult for such new mines to be built in BC? A conceptual framework of political ecology is used to determine the relationship between factors, actors and sectors in order to characterize their influence on mine development in BC between 1952 and 2014. The dissertation is organized in two parts: first, an analysis of economic, social and technological; and, (Part 2) political analysis. Part 2 analyzes seven current copper projects to determine their quality and economic viability. It analyzes the political factors, actors and sectors that are shown to have significantly influenced the development of mineral policy and regulatory frameworks in BC. This analysis showed that political, economic, social and technological forces (political parties, commodity prices, operating and capital cost inflation, environmental regulations, land access issues, environmental and social movements, and a change in voter values) have driven miners to restart or expand old mines rather than build new ones. It considers the potential consequences of what ultimately could result in a punitive cycle of discovery drought. In addition, factors, and actors need to come together in order for such large, low-grade deposits to be built in BC. Building a mine in the current climate is shown to be far more complex and regulated than at the height of BC mining development when Premier W.A.C. Bennett (1952-1972) was in power. The research demonstrates that significant development issues relate in particular to: First Nation land claims; the environmental movement and protected areas; regulatory duplication and inconsistencies; and provincial, federal and international relations that hinder mine development in BC. Overall, highlighting the decline in BC’s copper industry as being a political-economic issue opens up discussion and debate on how to resurrect the industry and how to make it sustainable for future generations.Applied Science, Faculty of

Full textAbstract:
This practice-based thesis is a study of the uneven geographical development of Chilean copper mining industry and the circulation of copper in Britain. My research examines three key historical moments in a pattern of ‘denationalisation,’ a term identified by Sassen (2003), of the copper resources of Chile: (1) 1840–1880; (2) 1904–1969; and (3) 1981–today, in which resources have been transferred from public to private management. In my research, I use a combination of photographic and historical methodologies to explore the impact of those processes on the extractive ecologies of Chile and to connect them to the global geographies of London, Liverpool and Swansea. My thesis considers how photography can be used to propose a re-mapping of the relationship between the global and the local, the national and the transnational, making visible the hidden geopolitical forces that shape the mobile and unequal geographies of copper. My doctoral investigation explores the global circulation of copper and its agency to produce geographical and political change. With the aim of revealing their close connections and networks, it examines the notion of ‘unequal geography’ established by Baran (1957) and the newer ‘mobility paradigm’ proposed by Sheller and Urry (2006). I follow the flow of copper, in Held’s words, ‘across space and time’ (1999), creating a constellation of photographs and texts about the transformation and mutation of copper as it traverses the world, exploring traces of extraction, smelting, manufacture, transport and trade processes across geographies. In doing so, I open ways of thinking about how landscape carries traces of those processes, bringing to the fore the significance of photographic intervention in highlighting them. The photographic research conducted during this investigation is organised in three lines of inquiry: Global mobility of copper; Post-industrial landscapes; and Contemporary mining industry and its relation to London. The first, Global mobility of copper comprises four visual essays presented together this written thesis: Sulphiric Acid Route (2012), Metallic Threads (2010-2015), High Rise (2012) and Hidden Circuits (2015). These works explore the mutation and transformation of hard-rock mining, back and forth from Chile to Britain from raw material to capital; through ore, smelted commodity, stock market exchanged value, assembled material and waste. The second, Post industrial landscapes, is explored through two case studies. The first of these is Coquimbo & Swansea (2014), which studies forgotten historical mining connections between Coquimbo, Chile and the Lower Swansea Valley, Wales between 1840 and 1880. This is followed by Miss Chuquicamata, the Slag (2012), which examines the Chuquicamata corporate town, Antofagasta Region, Chile and its contested history. The third line of inquiry, Contemporary mining industry and its relation to London involves two case studies. It opens with Antofagasta plc, Stop Abuses! (2010–14), which connects contemporary struggles of the inhabitants of Pupio Valley with the City of London, the world’s centre for mining investment. This line of investigation concludes with the site-specific studies LME Invisible Corporate Network (2011–15), which examines the London Metal Exchange within the City of London, using mapping methodologies. These case studies can also be used to map the three periods of denationalisation of copper resources in Chile. My photographic work is based on extensive photographic fieldwork in each geographical location, conducted over the last four years, as well as my two years as an activist photographer. Through my written thesis I seek to make visible the historical conditions that are central to the formation of the geographies of copper. Both aspects of my work are informed by the notion of ‘critical realism’ coined by Georg Lukács (1963) and developed later by Allan Sekula (1984). Alongside these case studies, my written thesis contains photographic examples of my practice so as to give insight into my research process. This thesis has been produced as part of Traces of Nitrate: Mining history and photography between Britain and Chile, a research project developed in collabotation with Art and Design historian Louise Purbrick and photographer Xavier Ribas, based at the University of Brighton and funded with the generous support of the Arts and Humanities Research Council (AHRC).

Full textAbstract:
The main parts of the production in the mining industry take place in different machines. These machines generate a big amount of data, which are being communicated, processed and stored for future processing. The mining industry goes through some changes in data processing. Today the main focus for the data processing is on the machines and the future goal is to redirect the main focus towards the mining technology. In the data processing this means standardization of the data processing so the data becomes uniform and easy to communicate between different processes. This system makes long time storage available for mining companies that use machines producing data exported as XML documents described by an Iredes XML Schema. The system provides automatic translation of the XML Schema into a database schema, which can then be populated by data from the machines. The first problem was to find a system that could translate the template XML Schema required. The best translator found was XMLBeans that translates an XML Schema into Java classes. The developed system translates these classes into an SQL script which generates the schema for the database. The translation is automatic, requiring no manipulation of the template; just some settings in the external XMLBeans are required.

Full textAbstract:
The strained commodity price environment has triggered strong measures of cost containment and control by global and South African mining industries with workforce reductions, mine closures and shelved projects. Added to this, the South African mining industry is facing an unparalleled number of challenges, including an uncertain regulatory environment, infrastructure constraints, frequent industrial actions, rising costs and shortages of skills. The dynamism of discontinuous change has increased considerably and the South African mining industry is today facing an uncertain future with a blurred outlook. The results of the detailed analysis of future studies theory and practice in this research study support the argument that there is a strong need to fundamentally change the ways of planning for the future of the South African mining industry. The practice of developing new insight through the application of futures studies is central to this process. Today, collective decisions and strategies are progressively more founded on and informed by futures studies. The research study sought to develop insight regarding the future of the South African mining industry through the construction of four scenarios towards 2055: Divided We Fall, where a confident industry is threatened by social divisions as industry transformation is disregarded; Rock Bottom, where weak global economic conditions coincide with lacklustre industry innovation; Rising from Ashes, with similar economic conditions, but the industry responding positively through accelerated industry innovation; and Renaissance, set against positive global economic conditions with the South African mining industry adopting a collaborative, innovative approach to industry transformation. The research study further strived to uncover the preferred future for the South African mining industry as basis for the South African Mine of the Future Vision towards 2055. Throughout the research study, Inayatullah’s pillars of futures studies were applied as a guideline in mapping the present and future, deepening the future, broadening the future through the development of scenarios, and transforming the future by narrowing it down to the preferred. The study provides valuable insight into the driving forces relevant to the South African mining landscape. In addition, it provides insight on how to anticipate the changes these driving forces may bring about for the industry over the next 40 years from a decision-maker’s point of view. It is up to the mining industry to select the road to follow in terms of progress and sustainable development. Through an innovative approach, the creation of an environment of trust, the sharing of values, purposes and benefits, the South African Mine of the Future Vision is attainable. The South African mining industry must commit itself to working in collaborative partnerships with local communities, government, society and labour; stepping boldly into a world of social, environmental, technological and commercial innovation.

Full textAbstract:
For many years Canada has been at the forefront of mining engineering education, research, and technology development. Canadian universities have been the foundation for developing the individuals and companies that have maintained a global reputation for quality and responsibility. However, various stresses on the Canadian mining education system currently appear to place at risk the quality of the educational experience, limit the ability of mining departments to adapt to industry, while overall jeopardizing the sustainability of mining education.
This study identifies the absence of an industry strategy to nurture the sustainability of Canada’s mining educational excellence. The thesis is based on a qualitative research program that examined the perspectives of a range of industry and academic experts. It attempts to contribute to invigorated collaboration between industry and universities to better address the future human resources challenges and ensure the sustainability of Canadian mining leadership.
Data collected through a series of structured interviews was organized into six themes leading to the conclusion that the challenges threatening the university contribution to mining engineering leadership in Canada can be mitigated through strategic university and industry collaboration.
It concludes that industry leadership needs to become proactively involved in collaboration with schools to sustain Canada’s mining education health and quality. Its leadership needs to be more aware of the critical state of Canadian mining engineering education system. Industry needs to influence mining schools to pool resources and expertise and to work collaboratively together rather than in isolation. Companies need to accelerate the development of future leaders through offering consistent summer student and co-op hiring. Lastly, it is recommended that industry needs to prioritize mentorship and facilitate the timely transfer of knowledge from senior engineers to junior engineers.
This thesis contends that Canadian mining engineering education is at a critical juncture. The mining industry is experiencing a new era of globalization and expectations of sustainable development. Continuing to simply stay the course places Canada’s competitiveness as a leader in mining at risk. The research concludes by observing that a new vision and strategy for industry-university collaboration, energised by government, should be a priority short term goal.Applied Science, Faculty of

Full textAbstract:
Corporate Social Responsibility (CSR) has frequently been discussed throughout the years. However, in the 1990s criticism of multinational companies and their production in developing countries resulted in new and more demanding requirements from society. Research within CSR has increased over time but scholars are now demanding research efforts on the practical rather that the policy level of CSR and in this thesis CSR practice is defined as the “ongoing, regular, daily activities of the organization”.It is commonly accepted that extractive industries are in the forefront of practicing CSR and CSR is significantly important in the mining sector. The research purpose is to explore how the extractive industry in general, and the mining industry in particular, is practicing CSR. A comprehensive literature review gave an overview of how CSR is put into practice in the extractive industry and two case studies gave more profound knowledge of the practical level of CSR in the mining industry. The ISO 26000 standard has been used as a framework consistently throughout the research process.The case studies gave information about the practical level of CSR in the mining industry and interesting similarities have been found. Both case companies have comprehensive policy frameworks on CSR. They also have standardized management systems according to OHSAS 18001 for occupational health and safety and ISO 14001 for the environment in order to fulfill legal requirements. When standardized management system standards, like ISO 14001, OHSAS 18001, and ISO 50001 for energy, have been implemented, the requirements within these areas in ISO 26000 are fulfilled. In other words, there is an overlap between the content in ISO 26000 and other system standards. A structured way of working towards continual improvements is missing for the core subjects: community involvement and development; and fair operating practices. It is also within these subjects that the majority of the potential improvements for enhancing CSR performance have been identified. Stakeholder management is an important part of CSR theory. If all core subjects are integrated into a sustainability management system that has adopted the structured way of working toward continual improvements, the system can be used as a basis for stakeholder management. The study has identified two areas of special interest for further research: stakeholder management related to standardized management systems and community involvement and development.Corporate Social Responsibility (CSR) eller företagens sociala ansvar som man säger på svenska har diskuterats i alla tider men på 1990-talet kritiserades multinationella företags verksamheter i utvecklingsländer något som resulterade i nya och tuffare krav från samhället. Forskning inom CSR har ökat succesivt men forskare vill se mer studier kring CSR i praktiken istället för på policy-nivå. I denna avhandling definieras CSR i praktiken som den ”pågående, regelbundna och dagliga verksamheten i en organisation".Det är allmänt accepterat att utvinningsindustrin har kommit längst i att praktisera CSR och att CSR är speciellt viktigt för gruvsektorn. Forskningssyftet var därför att utforska hur utvinningsindustrin generellt och gruvindustrin i synnerhet praktiserar CSR. En omfattande litteraturstudie gav en översiktlig bild över hur CSR praktiseras i utvinningsindustrin och två fallstudier gav djupare kunskap kring hur CSR praktiseras i gruvindustrin. Standarden ISO 26000 har konsekvent används som ramverk genom hela forskningsprocessen.Båda fallstudierna gav information om hur CSR praktiseras i gruvindustrin och intressanta likheter har identifierats. Båda fallföretagen har ett omfattande ramverk av CSR policys. De har också standardiserade ledningssystem i enlighet med OHSAS 18001 för arbetsmiljö och ISO 14001 för miljö för att uppfylla lagkrav. När ledningssystemsstandarder som ISO 14001, OHSAS 18001 och ISO 50001 för energi har implementerats så uppfylls också kraven för samma område i ISO 26000. Det finns alltså ett överlapp mellan innehållet i ISO 26000 och andra systemstandarder. Det strukturerade sättet att arbeta mot ständiga förbättringar saknas för huvudområdena; samhällsengagemang och utveckling samt goda verksamhetsmetoder. Det är också inom dessa områden som majoriteten av de potentiella förbättringsområdena för att öka CSR prestandan har identifierats. Stakeholder management är en viktig del inom CSR-teorin. Om samtliga huvudområden skulle integreras i ett gemensamt ledningssystem för hållbarhet, och det strukturerande sättet att arbeta mot ständiga förbättringar skulle införas, så skulle systemet kunna utgöra basen för stakeholder management.Studien har identifierat två intressanta områden för fortsatt forskning; stakeholder management i relation till standardiserade ledningssystem och samhällsengagemang och utveckling.

Full textAbstract:
The aim of this research study is to explore what ethical issues emerge in the Indonesian mining industry? What shapes the emergence of these issues and how do organisations engage with them? Many research studies (e.g. Dierksmeier, 2013; Bowie, 2002; Cragg, 2002; and Moberg, 1997) emphasise the relevance of ethical theories in understanding ethical issues in business organisations. However, there remains a significant gap in the business ethics literature in understanding ethical issues in a context-sensitive manner. There is little awareness in most of these studies of the influence of the social structure of a multi-ethnic and multicultural society like Indonesia or of the specific industrial and organisational contexts which are being explored. There is therefore a challenge for researchers to provide a conceptual framework to study ethical issues which will fit the Indonesian mining companies’ situation. This research employed Critical Realism (CR) and a qualitative approach. Data was collected from forty-eight participant interviews with managers and employees of four mining companies in Indonesia. This made it possible to understand what ethical issues emerge in the mining industry and to examine what shapes their emergence, as well as how mining companies engage with the ethical issues. The findings revealed that the companies’ ethical concerns result from the particular characteristics of the industry and the Indonesian national culture. However, their ethical concerns typically reside in risk management and regulatory compliance. The findings showed that cultural mechanisms shape the emergence of ethical issues in the industry: family perspective and paternalism, religiosity, and multi-ethnicity. The study findings suggest that the mechanisms shaping the emergence of ethical issues at the organisations presented at times conflicting cases of instrumental or possibly unethical behaviour but also evidence of set rules and regulations as well as moral awareness, practices aimed at considering others and stakeholders’ interests. This research argues that to understand the ethical issues and how business organisations engage with them in a multi-ethnic and multicultural context, it is essential to ground the conceptual framework in both ethical theories and specific cultural sensitivities, as only then can the full story be grasped.

ENGLISH ABSTRACT: The decision to make equipment replacements has a major influence on the competitiveness of any business. A company like Iscor recently spent approximately one billion Rand to modernise its fleet of equipment at various centres. This report presents a holistic approach to the issue of equipment replacement decision-making. It contends that equipment replacement decisions are not isolated incidents that occur by chance. In fact, the whole process is an integral part of the various processes in the business. This ranges from the influence on the strategy, through to issues such as production planning, maintenance, staffing, financial planning and so on. The role of the replacement decision in each of these elements are discussed and elaborated on. The report goes on to review the various models available in the industry and discusses their advantages and disadvantages. Thus ensuring a clear understanding of the differences in the approaches. The report attempted to propose a method that is relatively straight forward and in terms of application lends itself to the practical mining man. The proposed models are then used to complete a relatively simple example. The example was primarily aimed at showing the elements of the application and certainly not the full extent of the model.

Full textAbstract:
Gold mining communities in Ghana have experienced destruction of vegetation, water pollution, and soil contamination by activities of mining due to rapid growth and dependency on mining of natural resources within the catchment areas of the mining activities. These circumstances with repercussions of corruption and inefficient management of corporate social responsibility places organizational goals above the community and the nation. These setbacks necessitate the successful practice of corporate social responsibility to benefit stakeholders within mining communities. The purpose of this study was to investigate the relationships between corporate social responsibility, environmental policies, and community complaints, and the fiduciary responsibility to stakeholders. The research questions addressed whether a relationship existed between corporate social responsibility, environmental impact, community complaints, and the fiduciary responsibility to shareholders within gold mining companies in Ghana. Social exchange theory was the theoretical base of this quantitative correlational study, which included point-biserial and Spearman correlations to examine archival data from 10 active gold mining companies in Ghana. Results indicated a significant inverse relationship between community complaints and fiduciary responsibility, meaning that companies with positive report of community complaints tend to have lower fiduciary responsibility. Findings may inform policymakers, regulatory agencies, and mining organizations regarding the fiduciary effects of corporate social responsibility in the Ghanaian mining industry, and thereby influence positive business practices, living standards, and quality of life of Ghanaian citizens.

Full textAbstract:
Papua New Guinea (PNG) is a country possessing abundant resources of gold, oil, copper, timber, and fish stocks. It is hampered in its development and management of these resources, however, by serious problems of governance and corruption. These problems are evident throughout the economy and also in the management of the environment. The level of environmental damage caused by the mining industry in PNG is now such that it will require extensive rehabilitation, if the areas affected can, indeed, ever be fully rehabilitated. The mining companies which precipitated this damage were licensed and encouraged by the PNG Government in the initiation and exercise of the mining operations. The resulting environmental impact has affected the lives of thousands of New Guineans to their detriment. The degradation caused remains
unredressed.
Compounding the problem, there is a growing reliance by Papua New Guinea on mineral exploitation for foreign direct investment, government revenues, and foreign exchange. Gold exports accounted for the biggest share of export revenues in 2002 representing 37.5% of the total. In light of this growing dependency on mining activities, there is a correspondingly urgent requirement to address the deficiencies in the administrative, monitoring, and policing aspects of the protection of its environment.
Despite the public evidence of the damage to the environment and the ensuing affect on the people of Papua New Guinea by mining activities; and despite universal condemnation of these activities and the companies responsible; the companies continue to conduct these activities without official hindrance and with little apparent concern for the long-term ramifications of their actions.
This thesis will examine the degradation resulting from the mining activities of companies in Papua New Guinea over the last three decades - particularly those of Placer Dome's Porgera gold mine, BHP's Ok Tedi gold and copper mine (the waste from both of which is dumped into the Ok Tedi and Strickland rivers which are tributaries of the Fly River and form part of the Fly River system) and Lihir Gold Limited's gold mine on Lihir Island. It will examine the extent to which the Government of Papua New Guinea may have wittingly (in the sense of a prescience as to the possible or probable likelihood of deleterious impact) or unwittingly contributed to that degradation as a result of its actions or omissions.
Studies of available literature suggest that there has been little attention paid to the subject of culpability on the part of successive PNG governments in matters of environmental damage. This research will contribute to reducing this gap in the literature by focusing on possible motives of the PNG government and its actors which precipitated those decisions and which resulted in environmental degradation. The discussion will examine the likely motivation of the PNG government in its deliberations and decisions and the extent to which corruption and incompetence may have played a role.

Full textAbstract:
The problem addressed in the study concerned the lack of attraction of girls into professional Mining Industry (MI) careers. The study had four main objectives. The first was to review the literature to determine the reasons why there were so few women currently in MI careers, and then to describe strategies that have been successfully used to increase their participation. It quickly became apparent that while little research could be located relating directly to MI, the broader fields of science, engineering and technology (SET) could be reviewed to include the subset of mining-related careers.The second objective was to determine the attitudes towards MI careers of a select group of Year 10 schoolgirls, with the ability to proceed to the tertiary prerequisites for MI courses. This was accomplished through the development, implementation and statistical analysis of an instrument, the Mining Industry Attitude Survey (MIAS), designed specifically to focus on MI-related careers, rather than SET generally.The third objective was to develop and implement appropriate intervention strategies aimed at enhancing the attitudes of the group of girls, as determined through analyses of MIAS and related research. Under the auspices of the Western Australian School of Mines Engineering and Technology Camp, conducted annually in Kalgoorlie, a program of strategies was adapted and implemented over a period of five days at the residential camp.The final objective of the study was to determine if the intervention program did, in fact, enhance participating girls' attitudes. Using quasi-experimental research methods, quantitative data were collected and analysed from girls attending the camp, as the experimental group, and from applicants that did not attend as the control group. In addition, qualitative data were collected from select girls in the experimental group, during the camp program.The outcomes of the study are set out in terms of the main objectives, culminating in a discussion of the implications which the stated findings pose for researchers, practitioners of equity programs and employers of future MI graduates.

Full textAbstract:
Power grids have a high content of metal, mainly copper and aluminium. When old cables reach their end-of-life, or in some way lose their intended purpose, they are usually left lying in their subsurface position. Material no longer used, but not yet discarded as waste, is in a state known as hibernation. Over time there is an accumulation of hibernating cables under ground that potentially could be recovered or “mined”. The aim of this study is to examine the total hibernating metal content of an urban, subsurface power grid, how it is distributed and also what reasons for disconnection are the most common. The focus of the study is the power grid of Linköping. Using a GIS based variant of material flow analysis the hibernating metal stock is examined both in terms of size and spatial distribution. The results of the study show a significant amount of hibernating copper and aluminium; in total 240 tons of metal were identified. By comparing the results with previous studies both similar and differing patterns appear. The main differences lie in the distribution of the stock within the city which is affected by the characteristics of the cities. When examining the reasons for disconnection continuous repair and maintenance work seems to be the most common reason for disconnection of cables. Further studies on how the characteristics of a city affects the formation of hibernating metal stocks in the infrastructure are suggested.

There is limited research on the topic of outsourcing in the mining industry. The purpose of the study is to fill this gap and gain a general understanding of the state of outsourcing in the mining industry. The study seeks to answer basic questions such as how prevalent is outsourcing, what activities are being outsourced and why they are outsourcing. Upon surveying the upper management (e.g. CEOs and COOs) of 106 primarily Canadian mining companies with global operations, it became evident that outsourcing is widespread among both juniors and large mining companies. Some 89.7% of mining companies outsource or have outsourced in the past. Mining companies outsource mining more than mineral processing because mineral processing is a revenue generator and require large investments, which outsourcing suppliers generally do not have. Other popular activities for outsourcing include construction during mining operations. The biggest reason for outsourcing is access to specialized competencies, including skilled labour, followed by flexibility such adapting to seasonality, changes in geology and commodity prices. According to the criteria created by Quinn and Hilmer (1994), mining and mineral processing are not core competencies for mining companies and should be evaluated carefully for outsourcing although some 92.1% of mining companies perceive these activities as being core competencies. The seven traits of core competency put forward by Quinn and Hilmer were that they are: based on skills and intellectual property in the company; create flexibility; one of the top three capabilities of the company; fills a gap in the industry; performed better than providers; shareholders/customers care about them; and embedded in company processes. None of the traits reached the 92.1% agreement (to match the mining companies’ perception) necessary to be a core competency and therefore, mining and mineral processing are not core competencies for mining companies.Applied Science, Faculty of

The current discourse on public engagement in the mining industry revolves around legislated processes that drive communication and information sharing with interested parties. This discourse neither aligns with modern tools for communication nor with the reality of a highly networked society that use social media to facilitate dialogue. This thesis addresses the gap between traditional communication processes in the mining industry and social media tools that create opportunities for dialogue and information sharing.
The research used a qualitative and mixed method approach to data collection. Twelve social media websites were observed to assess the extent of mining-related dialogue, and 41 interviews were conducted with representatives from the public, private, academic and civil sectors to learn about the challenges and opportunities of using social media. The interviews found that 62% of respondents were using social media tools; the most popular applications were blogs, followed by social networking platforms. These platforms are being used for outreach to established supporters and networks. Industry’s use of these platforms mimics their public relations and marketing messaging approaches, whereas civil society is able to generate dialogue on a number of topics through authentic disclosure of information. Government departments have been hesitant to incorporate social media tools as they struggle to align them with regulatory structures while also presenting an authentic and credible voice. Many respondents were using a trial and error approach to implement social media, despite having identified risks of using them. Risks and challenges include the possibility of losing control of messaging and wasting time on unproven communications technology. While some mining companies are adopting social media applications to conduct public outreach, these tools have not been explicitly used for stakeholder engagement. Case studies show how mining stakeholders use social media tools and their experience provides a foundation for strategic recommendations. This research demonstrates that social media is being used for specific purposes by mining stakeholders, although there is hesitancy around perceived risks of online dialogue.

Full textAbstract:
This study investigated international technology transfer (ITT) of the coal mining industry in the Chinese context, and it focused primarily on how to achieve successful ITT by identifying affecting factors. The coal mining industry, as a dominant industry in China, hopes to achieve technological innovation and leapfrogging by ITT, because innovation distinguishes a leader from a follower and followers will have to continue purchasing technology from leaders. ITT is a complex process and many factors affect its success, so understanding of the affecting factors facilitates the industry to sufficiently learn and absorb foreign technology to achieve innovation. A number of researchers have studied the ways in which ITT can be achieved successfully in contexts other than the Chinese coal mining industry. However, in the Chinese context, it is still relatively unclear what factors affect the effectiveness of ITT. Owing to the scant literature on ITT in the industry, a pilot case studies was firstly designed and conducted with involvement of the following three types of coal mines: large state-owned, local state-owned and small coal mines. Then a main case studies was designed through observing these types of coal mines and conducting eighteen in-depth semi-structured interviews with general managers, general engineers and directors from the respective three coal mines. The aim of the design is to develop a substantial theoretical framework for generating hypotheses by combining extant literature with the findings of the pilot case studies. In addition, a self-completion questionnaire was designed based on findings from the case studies and then administered through a web-based survey in order to test hypotheses and identify the affecting factors. 629 questionnaires were collected from large stated-owned coal mines and they were analysed by multiple linear regression. Design of the survey enables the researcher to generalize the qualitative findings beyond the specific case. Data from the case studies and survey were used to triangulate perspectives and 5 findings. The main finding of the research revealed that the Chinese government made relevant safeguard regulations and punished IPR violation, which facilitated ITT. However, the government drew up encouragement policies and innovation strategies blindly based on its own visions or goals rather than the practical situation of coal mines; a number of managers of the coal mines interfered excessively with learning activities even without relevant background knowledge; and these interventions resulted in poor ITT performance. Furthermore, the large state-owned coal mine as transferee owned relevant background knowledge and provided relevant training to staff as well as building a good learning environment and establishing efficient team learning, which improved the effectiveness of its ITT. The theoretical contribution of this study lies in filling gap in the ITT literature in China and tested the generalizability of the existing theories. The findings suggested that a number of extant theories are not applicable to the Chinese context. In order to make extant theories better ‘fit’ into the Chinese context, this study suggests modifying extant theories based on government, technology management and team learning, which are three controllable and vital dimensions affecting the effectiveness of ITT in the Chinese coal mining industry.

Full textAbstract:
Tererotechnology evolved between 1970 and 1975. In 1968 PA Management Consultants Ltd., was commissioned by the then Minister of Technology of the UK to carry out a study of engineering maintenance in British manufacturing industry.
It reported that:-
a) the total direct cost of engineering maintenance was approximately 1, 100 Million Pounds per annum (circa 1968)
b) improved productivity of maintenance staff could have led to a reduction in
maintenance expenditure of around 250 Million Pounds per annum.
c) better maintenance could have saved about 300 Million Pounds per annum of lost
production caused by unavailability.
Using this and other information a UK Ministry of Technology working party reporting in 1970 emphasised among other things, the importance of the link between maintenance costs and the feedback of information to the designers of the plant. A steering committee ( The Committee for Terotechnology) was then set up to examine the broader findings of this report and in 1972
published their conclusions, central to which was the statement - "the nature of the maintenance activity was determined by the manner in which plant and equipment was designed, selected, installed, commissioned, operated, removed and replaced. Major benefits could come to British Industry from the adoption of a broadly based technology which embraces all these areas, and because no suitable word exited to describe such a multidisciplinary
concept, the name "terotechnology" (based on the Greek word "terin" - to look after) was adopted." In 1975 the Committee for Terotechnology defined terotechnology as follows:- " a combination of management, financial, engineering and other practices applied to physical assets in pursuit of economic life cycle costs."
The following was then added: " .... its practice is concerned with the specification and design for reliability and maintainability of plant , machinery equipment, buildings and structures, with their
installation and replacement, and with the feedback of information on design, performance and costs." (1)
The definition was subsequently utilised in BS.3811 1984.
The concept ofterotechnology is therefore, a total concept, colloquially called whom to tomb.
The Australian underground coal mining industry is a. two billion dollar a year industry, contributing greatly to the Australian economy, particularly the export economy. Appendix CI-1 gives an overview of the industry. (2)
Having spent over 30 years in the industry, most of which was in engineering and maintenance, I was acutely aware that the industry committed many millions of dollars maintaining its plant and equipment. I was also aware that the equipment design was, in the main, maintenance
unfriendly. Also, equipment failures were responsible for many lengthy and expensive delays resulting in interruptions to the production process and loss of production.
Whilst many endeavours were made to improve the situation, I became persuaded that a much deeper problem existed, the results of which were being addressed but little effort seemed to be spent on addressing the fundamental causes of the problems resulting in equipment downtime and its consequences. Having been exposed to the discipline of terotechnology through studies for a Graduate Diploma in Maintenance Management (Terotechnology), I sought to study the industry's perception of itself in the terotechnological perspective. This resulted in my initial industry survey in 1985, of its maintenance and its management. The results identified that indeed a problem did exist but
needed a more indepth and expanded industry analysis for the real details to be quantified. To my knowledge, no previous research has been conducted into the terotechnological aspects of the coal mining industry.
Consequently, the research was commenced through QUT for a Master of Engineering Degree.
This Thesis is the results of that research.
The research sought to address the fundamental issues addressed in the UK study and to determine if indeed similar savings could be achieved in the Australian coal industry. That is a) to determine the cost of engineering maintenance b) to detennine the maintenance cost savings achievable if maintenance could be improved.
c) to determine the costs of lost production costs through maintenance causes.
The research commenced by issuing a survey document in 1989 and followed this up with detailed analysis of coal industry records. Two visits to the USA in 1991 and 1992, to discuss
equipment performance and design with designers and users also contributed to the research.
The underground coal mining industry uses two basic methods of mining to mine the coal in Australia. One is Bord and Pillar extraction method using continuous miner systems and the other is Longwall extraction methods. The research concentrated heavily on continuous miners as they were identified as having the greatest impact on maintenance and productivity in the immediate
future. Longwall is the technology of the future analysed but to a lesser extent than continuous miners, as a detailed industry analysis was being conducted by the coal industry of this technology during my research of continuous miners. The Australian underground coal mining industry is being forced to become more world wide
competitive than at any time in its history. It follows therefore, that whatever the technology used
to produce the coal, the four elements of:-
a) Fit for purpose equipment b) Competent people
c) Safe work procedures
d) Controlled work environment
must be addressed. This is consistent with the terotechnological approach of this research.
Results of the research follow in this document.

Full textAbstract:
Each year, organizations in Australian mining industry (asset intensive industry) spend substantial amount of capital (A$86 billion in 2009-10) (Statistics, 2011) in acquiring engineering assets. Engineering assets are put to use in operations to generate value. Different functions (departments) of an organization have different expectations and requirements from each of the engineering asset e.g. return on investment, reliability, efficiency, maintainability, low cost of running the asset, low or nil environmental impact and easy of disposal, potential salvage value etc. Assets are acquired from suppliers or built by service providers and or internally. The process of acquiring assets is supported by procurement function.
One of the most costly mistakes that organizations can make is acquiring the inappropriate or non-conforming assets that do not fit the purpose. The root cause of acquiring non confirming assets belongs to incorrect acquisition decision and the process of making decisions.
It is very important that an asset acquisition decision is based on inputs and multi-criteria of each function within the organization which has direct or indirect impact on the acquisition, utilization, maintenance and disposal of the asset.
Literature review shows that currently there is no comprehensive process framework and tool available to evaluate the inclusiveness and breadth of asset acquisition decisions that are taken in the Mining Organizations.
This thesis discusses various such criteria and inputs that need to be considered and evaluated from various functions within the organization while making the asset acquisition decision. Criteria from functions such as finance, production, maintenance, logistics, procurement, asset management, environment health and safety, material management, training and development etc. need to be considered to make an effective and coherent asset acquisition decision. The thesis also discusses a tool that is developed to be used in the multi-criteria and cross functional acquisition decision making.
The development of multi-criteria and cross functional inputs based decision framework and tool which utilizes that framework to formulate cross functional and integrated asset acquisition decisions are the contribution of this research.

Full textAbstract:
Northwestern Mexico is characterized by different metallogenic provinces that are included along the Basin and Range, the Sierra Madre Occidental, and the Baja California geological provinces. With the purpose of contribute to the current understanding of the mineralizing processes, the present study focused on two important copper metallogenic provinces: the Cananea Porphyry District in Sonora, and the Sediment-hosted Stratiform Copper- and Mn-deposits in Baja California Sur. The U-Pb zircon ages from the mineralizing porphyries from Cananea district suggest a continued magmatic activity period of ~6 Ma. Also suggests a period of ~20 Ma for the entire magmatic activity in the district. The Re-Os molybdenite ages demonstrate five well-constrained mineralization events in the district; the main mineralization is constrained over a short period of time (~4 Ma). The new molybdenite age from the Pilar deposit documents the oldest mineralizing pulse, suggesting possibly the initiation of the Laramide mineralization in northern Sonora. A detailed study of Mariquita porphyry Cu and Lucy Cu-Mo deposits in the Cananea district was performed. Four hydrothermal stages were defined in Mariquita, whereas a single hydrothermal pulse characterizes Lucy. Emplacement depths between 1-1.2 km, and temperatures between 430-380ºC characterized the mineralization from Mariquita, whereas deeper emplacement depths and higher mineralization temperatures characterized Lucy. The stable isotope systematic and fluid inclusion data determined that the mineralizing fluids in Mariquita deposit are essentially magmatic during the earlier hydrothermal stages, whereas the last stage is the mixing between magmatic and winter meteoric-waters. The mineralizing fluids from Lucy deposit are magmatic in origin. A comprehensive study was performed in the Cu-Co-Zn-Mn ineralization of the Boléo District, and Mn-oxide mineralization along the eastern coast Baja California Sur. The REE and trace element in the Mn-oxides demonstrated the exhalative nature of the mineralizing hydrothermal fluids, and exclude the hydrogenous nature. The stable isotope systematic in ore and gangue minerals, along with the Cu-isotope data helped to decipher the nature of mineralizing and non-mineralizing fluids. The application of Pb, Sr and Re-Os isotope systems was applied to constrain the nature of the fluids involved during the mineralization processes and that the metal sources.
